[yocto] Yocto doesn't recognize cross-compiled binaries inside SDK

[Kun Yi]

Thanks for the explanation Alex! Will give the alternative you suggested a try.
As I understand I will need to instruct Yocto to fetch necessary
"native" toolchains and libs to compile the native variant recipe.
Doesn't that make my recipe non-portable to other host architectures?
